## Customer Reviews

### ⭐⭐⭐⭐⭐ Great light used as weld inspector
*by N***Y on December 4, 2025*

Size brightness and durability is great will buy another just to have.

### ⭐⭐⭐⭐⭐ Edc Flashlight
*by A***S on December 26, 2025*

Tough and Brite little flashlight. This is one of my top edc for work.

### ⭐⭐⭐⭐⭐ So bright you won’t need to power it on
*by A***A on May 17, 2024*

Perfect for on the job. I need a flashlight daily for work. This hits all the marks and more. My biggest concern is the button cap/switch. I have pushed these flashlights “raw” and the cap always breaks. This one solves that by offering replacement parts for purchase. I have dropped this light and have had no issue finding it on the ground and it continues to work. The stylus is only a name. It does not work as a stylus for touch screens. Another key feature was the size. I needed it to fit in my vest pocket where a pen would normally go and it’s perfect. The clip holds it securely in place as extra measure. The cap is oddly shaped and I’m not sure if it’s to get a better hold if you need to use your mouth to hold the flash light, but the plastic body makes that comfortable.
